What's New in Debt Book

1.0.25

September 16, 2026

Open Debt Book with a glance. NEW • Face ID and Touch ID unlock. If Debt Book is protected with a PIN, you can now unlock it with your face or fingerprint. Turn it on in Settings → Security → Unlock with Face ID. • Your PIN still works every time. Cancel the prompt, or tap Use PIN, and type it as before. • Part of Debt Book Pro, and available while password protection is on. • Your face and fingerprint stay with iOS — Debt Book never sees them, and the setting is not copied into backups. After a restore, Debt Book offers to turn it back on. • Reminders at an exact date and time. When you add or edit a transaction, Set Reminder now opens on your Settings default — days before, at your reminder time — and you can pick any moment up to the due date. Reminders you already set keep working as before. • Debt Book now speaks French. Choose Français in Settings → Language. FIXED • Clearing all data, importing a backup file or restoring from iCloud could close the app right afterwards. Fixed — the action had already finished, so your data was there when you reopened the app. • Backing up to iCloud no longer gets stuck on "Backing up…". If iCloud stalls, you now see a message and can try again. IMPROVED • A book name made only of spaces can no longer be saved, and spaces around a name are trimmed. • On devices without Apple Intelligence, the book screen no longer shows an error as soon as it opens. Name suggestions still work.
